I recently switched from a 8" Dob to a 11" SCT. I have an Orion Glass Solar Filter for my 8" Dob that I thought works pretty well. I'd like to get one for the SCT, and am wondering if there are any recommendations.
I've looked at the Orion Glass Filter, which i assume is the same as the 8" filter I have only bigger. I also found a company Thousand Oaks Optical that makes full apertures Glass solar filters, which come with a 15-year warranty.
Not sure if there others out there (that will fit my Celestron C11) that I should consider.
